Built for engineers using it for real design work. Go from concept to a running model in the browser, then scale to the cloud when needed. Simulate a service area live below — adjust the inputs and watch it respond, right in your browser.

Spatial Interpolation (IDW)Live

Controls

Presets

Given scattered measurements — rainfall gauges, soil samples, air-quality sensors — inverse-distance weighting estimates values everywhere in between. Each sample's influence falls off with distance raised to a power: a low power gives smooth, blended surfaces; a high power makes each sample dominate its neighborhood in sharp bull's-eyes. The workhorse of GIS mapping.

Governing equation

Reading this result: At power 2.0 nearby samples win but distant ones still contribute — a balanced surface between smooth and spiky.
